This one's complicated for me. I don't think true love is the hearts-a-flutter breathless 'in love' thing that often brings people together. I think that is a fleeting, hormonally produced condition of temporary insanity.

I think true love is when you would gladly clean up your beloved's vomit when he or she has the flu, and when the living of ordinary daily life, in all its forms, together, provides the meaning for your togetherness.

I think, when you have found someone with whom you would gladly do this, and who would gladly do it with you, you have found true love.

I do think it exists, but maybe it's rare.
